Re: [MW:3801] hydrotest b31.1

Dear Mr. Iordache,

 Although it is common practice not to coat weldings before hydrotesting, in practice the paint wil not prevent the water coming out in case of leakage. It is to be reminded, that the pipe system shall be presurized for considerable time, for example 24 hours, in order to let the fluid penetrate .
 
best regards,

Hi, 

I have a strange situation about Hydrostatic Test ......

Until now we used to let all welds of piping system no painted........

now our client read in B31.3 and open the discussion that in code is wrote that is allowed to paint the welds before hydrostatic test......

What do you think about that?????

regards
